Assistance Systems for Construction Site Safety: Revealing Static Forces for Deconstruction Processes

Abstract

High-performance tools and construction machinery generally involve a high accident risk. Currently, there are few assistance systems on construction sites that warn employees at an early stage of potential safety risks for man and machine. Sensors can be used to detect the movement of construction machinery, opening up opportunities for the development of assistance systems. In the demolition of concrete, powerful construction machines are used that work with high process forces. In this case, the construction machine generates a constant static force by which the cutting process is stabilized. The operators have no possibility to measure and adjust the static force of the construction machine in the planning and while the process. Evaluating the horizontal static performance at an early stage can prevent subsequent damage to the machine and ensures a safe working environment. Using the example of a (semi-) automated deconstruction machine, which can be controlled (semi-) automatically via ROS (Robot Operating Systems), a procedure was developed which enables the personnel to determine the static process forces for a safer work environment.
